The effects of water-miscible organic reagents such as ethanol, propanol, glycerol, acetic acid, ethylenediamine and triethanolamine on the signals of different mass and ionization potential were studied. Under optimized working conditions, the addition of a small amount of ethanol, propanol, glycerol, acetic acid, ethylenediamine or triethanolamine to the solution enhanced the signal of ionization energy at 9 ~ 11eV to some extent, The enhancing effect of amine or triethanolamine on Hg signal was significantly greater than those of ethanol, propanol and glycerol. The signal enhancement mechanism of ethylenediamine and triethanolamine to Hg was also discussed. Using the enhanced signal of Hg by ethylenediamine or triethanolamine, the Hg of the biological sample was determined. The method is quick and easy
